Still true at -r333575 : head -r320458 (e.g.) amd64 -> powerpc64 cross build's install32 during installworld: /usr/src/share/mk/bsd.linker.mk tried to use "head" when PATH provided no access (head is missing)

[Mark Millard]

Retrying the amd64 -> powerpc64 cross build via a powerpc64-gcc
this time, combined with WITH_LIB32= , got: "sh: head: not found" and its
later consequences, like before for installworld (to a directory on the
amd64 host context). This is from the /usr/src/share/mk/bsd.linker.mk line
that results in:

(/usr/local/powerpc64-freebsd/bin/ld --version || echo none) | head -n 1

but head is not available by default at the time (lib32 context). (I make
head be available via using LOCAL_ITOOLS=head in order to work around the
issue.)

An example of the messages (without having LOCAL_ITOOLS=head) is:

--- _installlinks ---
install -l s  ../../libexec/ld-elf32.so.1 /usr/obj/DESTDIRs/xtcgcc-powerpc64-installworld/usr/libexec/ld-elf32.so.1
cd /usr/src/usr.bin/ldd; PROG=ldd32 . . .
. . .
. . . MAKEOBJDIRPREFIX= MK_MAN=no MK_HTML=no  MK_TOOLCHAIN=no   -DLIBRARIES_ONLY  install
sh: head: not found
make[4]: "/usr/src/share/mk/bsd.linker.mk" line 47: warning: "(/usr/local/powerpc64-unknown-freebsd12.0/bin/ld --version || echo none) | head -n 1" returned non-zero status
make[4]: "/usr/src/share/mk/bsd.linker.mk" line 58: warning: Unknown linker from XLD=/usr/local/powerpc64-unknown-freebsd12.0/bin/ld: , defaulting to bfd


The two "make[4]" lines are consequences of the prior "sh: head: not found"
issue that leaded to a "non-zero status" independent of the prior "--version"
and "echo none" material. It then leads to assuming bfd.

Using LOCAL_ITOOLS=head makes head available and so then the status value
check works.
